Release Notes

This project rebuilds the viewer using 64bit address space. It is our hope that this will improve viewer stability, allow you to use more of the memory in your system (if you have more than 4GB), and possibly also improve performance.

This release has not yet been extensively tested; we are making it available somewhat earlier in the development cycle than usual so that you can help us find any subtle problems and measure the effect on viewer crashes.

There is no Linux viewer yet.

However, there are two Windows viewers, a 32-bit build and a 64-bit build. We expect the 32-bit Windows viewer to run more or less like the current release viewer. The 64-bit Windows viewer is more of an unknown quantity. We hope it will run like the current release viewer.

The Mac build has several known limitations:

We do not yet have a Havok build for 64-bit Mac. (And with this viewer, we drop support for 32-bit Mac.)

You will not be able to visualize pathfinding paths.

You may not be able to upload mesh assets.

Video media (QuickTime) does not play.

Note: Second Life 64bit viewer will not run on Win10 systems with Intel HD 2000/3000 GPUs and may not run on other systems that do not have GPUs explicitly supporting Win10.

Naturally we intend to address all these limitations before we ultimately release this viewer.
